Lungworm: (Dictyocaulus arnfieldi) infection in donkeys

Veterinary Record, 1979
The clinical, parasitological and pathological findings in a group of six donkeys naturally infected with D arnfieldi larvae are described. One animal had to be sacrificed at an early date because it developed pneumonia. The remaining five were unthrifty, showed mild clinical respiratory signs and had heavy strongyle infections.

Cross Resistance to Dictyocaulus viviparus Produced by Dictyocaulus filaria Infections in Calves

Research in Veterinary Science, 1967
SUMMARY Calves which were infected with Dictyocaulus filaria were more resistant to a challenge infection of D. viviparus than previously uninfected animals. The reduction in the D. viviparus worm burden was 67% at 10 and 24 days, and 76% at 30 days after challenge.

Radioactive Antibody Studies on Dictyocaulus filaria Infection

Research in Veterinary Science, 1971
SUMMARY Rabbit anti-sheep 7S immunoglobulins labelled with 131I were used for the estimation of immunoglobulin binding to the juvenile stage of Dictyocaulus filaria. The method showed the ability to detect the quantity of specific antibodies in sera of lambs infected with D. filaria.

Local cytokine responses in Dictyocaulus viviparus infection

Veterinary Parasitology, 2005
The high degree of immunity induced by the bovine lungworm, Dictyocaulus viviparus, makes it an ideal model in which to study nematode-induced protective immune responses. Here, cytokine responses were measured over the course of an experimental infection of D. viviparus. Local cytokine messenger RNA (mRNA) transcripts were measured in lung parenchyma,

Dictyocaulus infection in farmed red deer (Cervus elaphus)

Veterinary Record, 1980
Post mortem examination of red deer calves on a deer farm situated on hill ground in north-east Scotland revealed infection by a lungworm morphologically similar to Dictyocaulus viviparus. Trials were conducted to monitor the natural development of D viviparus infection in red deer, to investigate the value of a commercial lungworm vaccine and to ...

Chronic Respiratory Disease in a Horse Infected with Dictyocaulus arnfieldi

Journal of the American Veterinary Medical Association, 1981
A 6-year-old Thoroughbred gelding was examined because of respiratory disease that developed after it was placed on pasture occupied by a donkey. Clinical signs in the gelding included a harsh, dry paroxysmal cough and increased expiratory effort. Eosinophils were seen in smears of mucus aspirated from the trachea and the bronchi.

Experimental studies on anaemia in sheep infected with Dictyocaulus filaria

International Journal for Parasitology, 1989
The pathogenesis of Dictyocaulus filaria induced anaemia was experimentally investigated. Nineteen Dorset-Muzaffarnagri male lambs were divided into two groups of 13 and six. The lambs in the former group received a primary infection dose of 2000 D. filaria infective larvae, whereas animals in the latter group were kept as uninfected controls.

Dictyocaulusspecies: cross infection between cattle and red deer

New Zealand Veterinary Journal, 2003
To discover whether cross infection between red deer (Cervus elaphus) and cattle is possible with either a bovine isolate of the cattle lungworm, Dictyocaulus viviparus, or with a cervine isolate of the lungworm, Dictyocaulus eckerti which is thought to be maintained primarily in deer.Twelve cattle and 12 red deer were reared parasite-free from birth ...

Natural infection with Dictyocaulus arnfieldi in pony and donkey foals

Research in Veterinary Science, 1981
From June to October 1978 four pony mares and foals and two donkey mares and foals grazed a paddock contaminated with Dictyocaulus arnfieldi larvae. No signs of respiratory disease were seen in the foals but within 11 weeks of exposure to the paddock all six developed patent lungworm infections. In October 1978 one donkey and two pony foals were killed.
